WebThe critical micelle concentration of surfactants has been reported using various techniques such as conductivity, surface tension and fluorescence measurements [3-5]. Dynamic light scattering is a technique well suited for the determination of the cmc. In the results summarized here, measurements were made of different concentrations of triton ... WebThe critical micelle concentration (CMC) is defined as the concentration above which micelles form. At low surfactant concentration the surfactant molecules arrange on the surface. When more surfactant is added the surface tension of the solution starts to rapidly decrease since more and more surfactant molecules will be on the surface. chin\u0027s ea https://ninjabeagle.com
